Specification of Letters Patent.

Continuation of application Serial No. 93,182, filed April 24, 1916.This application filed February 9, 1917. Serial No. 147,542.

To all whom it may concern Be it known that I, CLAIR V. RUGKER, acitizen of the United States, and a resident of the borough ofManhattan, city, county, and State of New York, have invented certainnew and useful Improvements in Packets for Transparent Bulletins, ofwhich the followingis a specification.

The object of my invention is the production, as an article ofmanufacture, of a flexible packet of parts essential to the formation ofa transparent bulletin for use as a component part of a lantern orprojector slide,the distinctive feature being the formation of theexternal wrap with a detachable mat section, which is eventuallyincorporated with the imprinted transparent bulletin film in thecompleted slide,said mat-section afiording the triple function of anopaque margin to a centralized aperture which permits direct accessthrough the outer wrap for effecting the imprint on the transparentfilm; of acting as a guide in imposing the imprint on said film; and ofprescribing the light aperture in the completed slide, all ashereinafter fully set forth.

In the accompanying drawings,

Figure 1, is a view of a blank of the external or wrap member of myimproved flexible packet for transparent bulletins, the blank beingspread out flat and showing the inner side thereof;

Fig. 2, is a view of the carbon or other transfer sheet used in thepacket, broken away in part;

, Fig. 3, is a view of the sheet of flexible transparent medium;

Fig. 4, is a view illustrating the relative positions of the transparentmedium and the transfer sheet or folder;

Fig. 5, is a front view of the packet as folded together and ready foruse for the formation of a transparent bulletin;

Fig. 6, is a rear View of same;

Fig. 7, is a section taken upon plane of line 7-7, Fig. 5;

Fig. 8, is a diagrammatic illustration of the adaptability of the packetto the platen of a typewriting machine;

Fig. 9, is a view of the transparency and the mat portion of the packetincorporated in a lantern slide;

rig. 10, is a transverse sectio hereof taken upon plane of line 10-10,Fig. 9;

Fig. 11, is a view of the mat front detach'ed from the wrapper.

The blank of the external wrapper or folder F, is made of any suitableflexible material, as thin tough paper, and is shown as spread out flatin Fig. 1, by reference to which it will be seen that it consists of theback section f, front or mat section 7, and the securing flap f ,theprescribed lines of fold and severance f 7, being formed each by aseries of perforations, indentations or other means for facilitating thefolding and subsequent detachment of the sections of the folder F,(considered as a whole) the one from the other, particularly the finalseverance of the face or mat section 7, from the back 7, and from thesecuring flap f which may be provided with an adhesive a, forincorporation with the prepared transparent medium t, in a lantern slideas herein set forth. For this reason the mat or face section f, of thewrapper or folder F, is formed with the sight opening or exposure spaceF, the edges of which finally constitute the mat or opaque section 7, ofthe lantern slide S, shown more particularly in Figs. 9, and 10.

The light-transmitting medium or film t, on which the lettering or otherlineal matter of the bulletin is to be impressed, is a sheet, (slightlyless in size than the folded Wrapper F,) of flexible transparentmaterial of any desired or suitable character adapted to take imprintfrom the carbon or other transfer sheet 0, which is interposed, when thelatter is written upon either by hand implement, typewriter keys, orother means. This printable flexible transparent medium t, is preferablyinserted between the leaves of a fold of suitable transfer paper 0, 0,as indicated in Fig. 4, prior to introduction in the folded wrapper F,the

flap P, of which, as above described may be provided with an adhesive a,for positive attachment to the back f, if desired, or it may be simplyfolded over the edge of the back f, sufficient overlap being provided toinsure the requisite degree of closure between front f, and back 7, atthis edge of the package.

The packet E, thus constituted is sufficiently pliable to adapt itselfto the peripheral surface of the platen 1', of a typewriting machine asindicated in Fig. 8, so that the matter to be bulletined may be thusimprinted on the transparent medium t through the medium of the transferpaper 0, or, as before intimated, the latter may be written upon by penor other hand implement adapted to transfer the characters to thetransparent medium 25. Or if the surface weakened lines of severence f,7, thereby releasing also the face or mat section 7, 0f the wrapperF,the said prepared transparent medium 25, and the said mat section f,being then incorporated in a lantern slide S, by placing them betweentwo sheets of lantern glass, mica, or other suitable transparentmaterial 8, s, the edges of which are bound together by adhesive tape 8,or equivalent means, as indicated in Figs. 9, and 10, thereby forming aslide adapted to all the requirements of practical use in lantern orprojecting apparatus.

It is obvious that but a single ply of transfer paper 0, or equivalent,may be used for effecting the imprint upon the transparent medium 2?,but I prefer to use two thicknesses thereof between which thetransparent film t, is interposed as in the drawings, because in thisway I get coincident imprints on both sides of the transparent medium,thus attaining a maximum of opacity for the matter bulletined, and thusinsuring the best results of contrast vbetween light and shade when thebulletin is projected on the screen.

It is also obvious that the back section 7", as Well as the frontsection f, of the wrapper F, may be formed with the mat opening 7, if sodesired, both mats thus provided to be utilized in the formation of theslide S, one for each side of the transparent medium 25, but this ismerely a matter of detail or preference, the result being essentially,

the same whether one or two mat borders f, are provided or used.

It will be seen that the sight opening F, in the front mat section f, ofthe wrapper Copies 0. this patent may be obtained for F, afiords directaccess to the carbon or other transfer medium 0, so that immediatecontact therewith ma be had in forming the imprint upon the transparentmedium 23, or if the latter is susceptible of receiving impre'ssionfromthe ink ribbon of a typewriter and the transfer sheet 0, is omitted ashereinbefore intimated, then in that case the opening f admits ofthe'contact' of the ink ribbon with the surface of the film 25, thusinsuring the best results as to clearness of impression'etc, In otherwords the opening 7, in the front or. mat section 7", of the wrapper F,eliminates one thickness of paper or similar material that wouldotherwise be interposed between the film t and the marking implement,causing blur or indistinctness of outline. r V

This direct access for the-marking implement tothe transfer medium bywhich the film t, is impressed also adapts the device for the imposingof diagrams, outlines or other drawings distinctly upon the film, andextends the field of usefulness of the article of manufacture.

Furthermore, the inner edges of thefborder f act as guides forprescribing and positioning the imprint on the transparent to secure byLetters Patent is,

A wrapper for a packet for transparent bulletins in which the bulletinis imposed on a transparent film from a transfer sheet folded about thefilm and inserted in a folded wrapper, which consists of a flexibleopaque wrapper folded midway of its length and having a weakened line atther fold, one of the leaves of the wrapper being What I claim as myinvention and desire V provided with an exposure opening whereby thebulletinrmay be produced by direct action on the transfermaterial andwhereby the leaf having the exposure opening may be detached at the lineof fold and used as a mat for the film when it is used as a lanternslide.
